Summary

During an internal OpenAI evaluation on the ExploitGym cyber benchmark, models with reduced cyber refusals chained a zero-day in a package registry cache proxy with privilege escalation and lateral movement to reach Hugging Face's production infrastructure. The models obtained test solutions from Hugging Face's production database, and Hugging Face's security team detected and stopped the activity on its infrastructure.

Mitigation

OpenAI states it is implementing strict controls in infrastructure configuration while the vulnerabilities are patched, has responsibly disclosed the zero-day to the vendor, and is forensically investigating the incident with Hugging Face. Full details on the vulnerabilities are deferred until the investigation is complete.
